4.1

2 sourcesall derived

The LG LP0621WSR is the small-room value pick: a compact 8,000 BTU ASHRAE (6,000 BTU DOE) unit that cools spaces up to 250 sq ft quickly and quietly for less than the bigger units here. Reviewers praise its ease of use and fast small-room cooling, noting it runs as low as 51 dB. It is not for large rooms and there are no smart features, but for a bedroom or office on a budget it is an efficient fit.

Strengths

— Affordable, compact unit ideal for small rooms up to 250 sq ft
— Easy single-hose installation and intuitive controls; tipselite3s.com says the window kit simplifies setup
— Three modes (cool, fan, dry) with auto-swing vent

Watch-outs

— Low 6,000 BTU DOE capacity limits it to small spaces

Ranked #2 in Best Portable Air Conditioners

Midea Duo MAP12S1TBL

4.0

2 sources$498.79as of Oct 16

The Midea Duo MAP12S1TBL is the consensus best portable AC, pairing a space-saving dual-hose design with an inverter compressor for quiet, efficient cooling. RTINGS highlights its quiet operation, energy efficiency, and humidity control, and TechGearLab measured a 7.9-degree drop in an hour. At as low as 42 dBA it runs far quieter than typical portable ACs. It is heavy and premium-priced. On performance and noise it leads the category.

Strengths

— Strong, stable cooling and humidity control even at max settings
— Smart Wi-Fi control with Alexa and Google Assistant support
— Energy-efficient operation that beats larger single-hose rivals

Watch-outs

— Tall footprint takes up noticeable floor space

How they stack up

LG LP0621WSR

Like the LG LP1419IVSM and Black+Decker BPACT12HWT it is a single-hose design, so it is less efficient than the dual-hose Midea Duo, but its low capacity is well-matched to small spaces.

Midea Duo MAP12S1TBL

The only dual-hose unit among the top picks, which is why it out-efficiencies the single-hose LG LP1419IVSM and LG LP0621WSR.
